wraps the browser's native event-object normalizing cross-browser differences,
such as which mouse button is clicked, keys pressed, mechanisms to stop
event-propagation along with a method to prevent default actions from taking place.
<p>For example:</p>
<pre><code><b>function</b> handleClick(e, t){ <i>// e is not a standard event object, it is a Ext.EventObject</i>
    e.preventDefault();
    <b>var</b> target = e.getTarget(); <i>// same as t (the target HTMLElement)</i>
    ...
}
<b>var</b> myDiv = <a href="output/Ext.html#Ext-get" ext:member="get" ext:cls="Ext">Ext.get</a>(<em>"myDiv"</em>);  <i>// get reference to an <a href="output/Ext.Element.html" ext:cls="Ext.Element">Ext.Element</a></i>
myDiv.on(         <i>// <em>'on'</em> is shorthand <b>for</b> addListener</i>
    <em>"click"</em>,      <i>// perform an action on click of myDiv</i>
    handleClick   <i>// reference to the action handler</i>
);
<i>// other methods to <b>do</b> the same:</i>
Ext.EventManager.on(<em>"myDiv"</em>, <em>'click'</em>, handleClick);
Ext.EventManager.addListener(<em>"myDiv"</em>, <em>'click'</em>, handleClick);</code></pre><br><br><i>This class is a singleton and cannot be created directly.</i></div><div class="hr"></div><a
